This paper presents an overview, based on field data, of the adpositional system in Akebu, a Kwa (Ghana-Togo Mountain) language of West Africa. Like other Kwa languages, Akebu has both linear types of adpositions. Prepositions are not numerous and are fully grammaticalized. Two prepositions are used very widely, one of them expressing a comitative meaning and a number of related ones, the other having a generalized locative meaning, as well as other ones. In contrast, postpositions are more numerous, but most of them are weakly grammaticalized relator nouns that express the meanings of locational orientations and keep nominal morphology and independent uses. Still, grammaticalized postpositions are also present, the most common of them being a postposition that expresses apudessive, i.e. near, next to, orientation.

阿克布语中的介词和介词关系名词

本文根据实地数据概述了阿克布语（西非夸纳语（加纳-多哥山地）语言）的附加系统。与其他夸语一样，阿克布语也有两种线性类型的介词。介词数量不多并且完全语法化。有两个介词使用非常广泛，其中一个表达连词意义和一些相关的意义，另一个具有广义方位意义，以及其他意义。相比之下，后置词数量较多，但大多数是弱语法化的关系名词，表达位置方向的含义，保留名词形态和独立用途。尽管如此，语法化的后置词仍然存在，其中最常见的是表达贬义的后置词，即靠近、旁边、方向。
